Response to letter of Dawson J. A, Brown A. W and Allison D. B: intervention for childhood obesity based on parents only or parents and child compared to follow-up alone

摘要

We are pleased to have the opportunity to respond to the letter of Dawson J. A, Brown A. W and Allison D. B. in regard to our recent paper. We conducted a three-arm parallel randomized controlled trial (RCT). Participants were randomly assigned to one of three groups: a control group or one of two behavioural interventions, towards either both parents and children or parents only. Our primary outcome was change in BMI-SDS after 3 months of intervention and after 24 months of follow-up. The pair-wise results (using paired-samples t-test as well as in the mixed model regression adjusted for age, gender and baseline BMI-SDS) showed significant decrease in BMI-SDS in the parents-child group both after 3 and 24 months, which indicate that this group of children improved their BMI status (were less overweight/obese) and that this intervention was indeed effective.
